So my 1976 FJ40 project came in pieces in boxes. I have finally got around to the electrical box. I have no idea what these things are and if I need to use them, replace them or what. Any help would be appreciated. I am installing a 2F out of a 1987 FJ60 to replace the SBC motor set up if that helps things a bit. The small black box says it is a seat belt warning device. The small gold cube says it is a buzzer. Not sure about the others.
